Salicylic acid protects the skin from UV damage

J Cosmet Sci. Mar-Apr 2006;57(2):203-4.


Aspirin(acetyl salicylate) has long been used as an analgesic. Salicylic acid has been reported to have anti-inflammatory properties. These activities include inhibiting activity of cox-1, cox-2, and NF-kb. In addition, salicylic acid has also been shown in some systems to induce Hsp70. We have demonstrated that salicylic acid inhibits UVB-induced sunburn cell formation, as well as increase the removal of UVB induced TT dimer formation in living skin equivalents. Given these protective properties of salicylic acid, we propose the use of salicylic acid as a topical therapeutic to protect the skin from sun damage.
